The equation that shows the monthly cost is y = 9 + 3x
What is the equation that represents the monthly cost?
The monthly cost is a function of the charge for a single user and the cost of additional users. The monthly cost increases with the number of additional users.
The charge for a single user can be considered a fixed cost since it remains constant while the cost of the additional user can be considered a variable cost since it increases with the number of users.

Given equation: 1/4(x - 2) = 3 - (x + 1/6)Simplify the distributive property.
1/4(x - 2) = 3 - (x + 1/6)=> x/4 - 2/4 = 3 - x - 1/6Further simplify both sides.
x/4 - 2/4 = 17/6 - xSubtract 17/6 both sides.
x/4 - 2/4 - 17/6 = 17/6 - 17/6 - x=> x/4 - 6/12 - 34/12 = -x=> x/4 - 40/12 = -xSubtract x/4 both sides.
x/4 - x/4 - 40/12 = -x - x/4=> -40/12 = -5x/4Use cross multiplication.
=> -160 = -60xDivide -60 both sides.
-160/-60 = -60x/-60=> x = 160/60 = 2 40/60 = 2 2/3Find the sum of the following arithmetic sequence. 4,10,16,22,28
Answer:
Step-by-step explanation:
This is the formula to find the sum of the first
n
terms of the sequence. To evaluate it, the values of the first and
n
the terms must be found .Sn=n2⋅(a1+an)
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
6
to the previous term in the sequence gives the next term. In other words,
an=a1+d(n−1)x Arithmetic Sequence:
d=6 This is the formula of an arithmetic sequence X an=a1+d(n−1)Substitute in the values of a1=4 and d=6 x an=4+(6)(n−1)Simplify each term.
an=4+6n−6 Subtract 6 from 4 x an=6n−2 Substitute in the value of N to find the N the term x a5=6(5)−2 Multiply 6 by 5 x a5=30−2 Subtract 2 from 30 x a5=28 Replace the variables with the known values to find
S5 x S5=52⋅(4+28)Add 4 and 28 x S5=52⋅32
Cancel the common factor of
2.
S5=5⋅16 Multiply 5 by 16 x S5=80
Convert the fraction to a decimal.
S5=80

Answer:
3 3/16 meters
Step-by-step explanation:
The volume of the box is the product of the length and width and height. You are given the length, and you are given a relation for the width. To find the height, you need to use the given relations to create an appropriate equation to solve.
One way you can do it is this:
V = LWH
If we use a value that is (1 9/16)W, then we have ...
(1 9/16)V = L·(1 9/16)W·H . . . . . multiply the above equation by 1 9/16
Putting the given values into this relation, we have ...
(1 9/16)(12 3/4) = (2 1/2)(2 1/2)·H . . . . . . remember, 2 1/2 = (1 9/16)W
H = (1 9/16)(12 3/4)/(2 1/2)² = (1275/64)/(25/4) = 51/16
H = 3 3/16 . . . meters
__
Additional comment
An alternative is to find the actual width:
(1 9/16)W = 2 1/2
W = (5/2)/(25/16) = 8/5 = 1 3/5
Then you would have ...
12 3/4 = (2 1/2)(1 3/5)·H = 4·H
H = (51/4)/4 = 51/16 = 3 3/16 . . . as above
Dario purchased a party size sub, and he decides to share it with 3 of his friends. So, he cuts the sub into 4 equal pieces. However, another one of his friends also showed up, and there are now 5 people in total.
Part A
Now that the sub will be shared equally among 5 people, will each person get more or less sub? Briefly state why you think so.
Part B
Dario decides to take each one of the 4 pieces and share it equally among the 5 of them. First, he divides one piece into 5 equal parts and shares it, then the next one, and so on.
What fraction of the party size sub did each person get after all the parts were shared out? Briefly explain your reasoning.
The fraction illustrates that each person will get less sub since there are more people sharing it.
How to explain the fraction?In this case, Dario purchased a party size sub, and he decides to share it with 3 of his friends but another friend came. This means there will be less in to be shared.
The fraction of the party size sub did each person get after all the parts were shared out will be:
= 1/5 × 4
= 4/5
Therefore, each person gets 4/5.

Chase found new pants for $35.55 plus 7.5% tax. What is the final price of the new pants?
Answer:
$38.22
Step-by-step explanation:
7.5% of $35.55 = $2.66625
= $2.67
$35.55 + 2.67 = $38.22 after tax
Answer:
$38.22
Step-by-step explanation:
Given the following question:
7.5% of 35.55
To find the answer we must first find 7.5% of 35.55 using the formula to calculate percentages, and then we add that answer to the current price of the pants.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7.5\times35.55}{100}[/tex]
[tex]7.5\times35.55=266.625[/tex]
[tex]266.625\div100=2.66625[/tex]
[tex]=2.66625[/tex]
Round the answer to the nearest cent:
[tex]2.66625[/tex]
[tex]6 > 5[/tex]
[tex]=2.67[/tex]
7.5% of 35.55 is "$2.67."
Now we add the answer to the current price:
[tex]35.55[/tex]
[tex]35.55+2.67=38.22[/tex]
[tex]=38.22[/tex]
The cost of the new pants after a 7.5% tax is "$38.22."

Calculate the probability for the following situation: You are tossing a coin, then rolling a die, then drawing a card from a deck of cards. What is the probability that you will get: a head AND an odd number on the die AND a card greater than 3 (assume the ace is equal to 1) from the deck?
Answer:
Flipping the coin:
P( H ) = 1/2
---------------------
Rolling the die:
There are 6 numbers
1,2,3,4,5,6
3 of them are odd, so
P( odd ) = 3/6
P( odd ) = 1/2

Find the exact value of the trigonometric function given that sinU=-7/25 and cosV=-4/5 (Both U and V are in Quadrant III)
sin(V-U)
cos(U-V)
cosU:-
[tex]\\ \rm\longmapsto \sqrt{1-sin^2U}=\sqrt{1-49/625}=24/25[/tex]
As U lies in Q3
cosU=-24/25sinV
[tex]\\ \rm\longmapsto \sqrt{1-cos^2V}=\sqrt{1-16/25}=3/4[/tex]
As V lies in Q3
sinV=-3/5So
sin(V-U)=sinVcosU-cosVsinU=(-3/5)(-24/25)-(-4/5)(-7/25)=72/125-28/125=72-28/125=44/125cos(U-V)=cosUcosV+sinUsinV=(-24/25)(-4/5)+(-7/25)(-3/5)=96/125+21/125=117/12536 ÷ 2² × 4² this is my question guys:)

Which of the following fractions is equivalent to 1.68? A. 25/42 B. 17/25 C. 42/25 D. 7/4
Answer:
42/25 or C
Step-by-step explanation:
Just by looking at the answers, we can eliminate A and B because the equivalent decimals of those would result in a number that is less than one.
Then, you can eliminate D because 7/4 is equal to 1.75
Therefore, your answer would be C, 42/25.

A phone company offers two monthly plans. Plan A costs $15 plus an additional $0.14 for each minute of calls. Plan B has no initial fee but costs $0.18 for each
minute of calls.
Step-by-step explanation:
x = number of minutes
first cost function :
c(x) = 0.14x + 15
the second cost function :
c(x) = 0.18x
I guess, the question (not written in the description) is after how many minutes call time the first plan breaks even with the second plan and further becomes the better choice ?
0.18x = 0.14x + 15
0.04x = 15
x = 15/0.04 = 375
with 375 minutes calling time per month the first plan costs the same as the second plan.
and starting with 376 minutes per month the first plan becomes the cheaper option.
under 375 minutes per month the second plan is the cheaper option.
